who cares... its still hang... and press home butoon... wait 2-3 second only goes to home... quad core apa la...

try iphone 4 press home, any apps also instant exit... thats the difference...

OMG!
you dunno anything but u are flaming it like no other day.

the lag on home button for the s3 is due to the launching of S-voice. double press on the home button will launch S-voice.

when u press once on the home button, the phone waits for a 2nd input to see whether u wanna launch S-Voice or not.

You can disable this feature on S-Voice. and it will be buttery smooth.

anyway, speaking of buttery smooth. watch some videos about Android 4.1.1 Jelly Bean.

Do some research before spouting crap.
